2.3.2.Serial package method
Figure 10 Serial package method
Suppose n ms is serial package triggering time, if T1>n, T2<n, T3<n, T4<n, T5<n, T6>n, Byte1-Byte5 will be a
package.
Transparent transmission mode: In transparent transmission mode, W600 will continually check the
interval between two adjacent bytes. If this interval > serial package triggering time(Default is 20ms and
user can use AT+UARTTE to configure triggering time), it will be considered as end of a package and W600
will send received data as a TCP package data to network. Otherwise W600 will receive data to 1024 bytes
and send these 1024 bytes as a TCP package data to network.
AT command mode: In AT command mode, W600 will continually check the interval between two adjacent
bytes. If this interval > serial package triggering time(Default is 20ms and user can use AT+UARTTE to
configure triggering time), it will be considered as end of a package and W600 will parse this package in AT
command format. Otherwise W600 will receive data to 256 bytes and return command error.
2.3.3.Baud rate synchronization function
When module works with USR devices or software, serial parameters will change dynamically according to
network protocol. User can modify serial parameters by sending data conformed to specific protocol via network.
It is temporary, after resetting module, the parameters will back to original parameters.
